"Zhong Wang Yan Liu" in the Yin Dynasty replaced those historians who carved Oracle Bone Inscriptions. It is they who left a wealth of historical materials and precious ancient calligraphy works for future generations. If we take a cursory look at Oracle Bone Inscriptions's calligraphy forms, we will find that the early fonts are very large, such as many Oracle Bone Inscriptions in the Wuding period included in Luo Zhenyu's Book of Yin Ruins Qi Jing Dialect, which are very atmospheric and eye-catching; By the time of Di Yi and Di Xin in the last years of Shang Dynasty, the characters became small and trivial.
